4. solve this system of equations using substitution:
y = 2x - 4
x + 2y = 10
complete steps in the box provided.
step 1: substitute for why i the second equation. which
is the resulting equation?
step 2: which is the next step to solve for x?
step 3: which terms can be combined to isolate the
variable term the left side?
step 4: which step isolates the variable term on the left
side?
step 5: which step isolates the variable term on the left
side?
step 6: to solve for y, substitute 3.6 for x in the
equation.
step 7: which is the y-value in the solution?

This Is The Best I Could Do For You:

Solve for the first variable in one of the equations, then substitute the result into the other equation.

Point Form:

( 18  / 5 , 16  / 5 )

Equation Form:

x  =  18  / 5 ,  y  =  16 /  5

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
