How do i solve system of equations by substitution
y=-2x+2
y=7x+11

(-1, 4)

Step-by-step explanation:

We are told that:

y = -2x + 2 and

y = 7x + 11.

We can eliminate "y" by setting these two equations = to each other:

-2x + 2 = 7x + 11.

We need to solve this equation for x.

Adding 2x to both sides, we get 2 = 9x + 11.

Subtracting 11 from both sides results in -9 = 9x.  Thus, x = -1.

Find y by subbing -1 for x in either of the given equations.

If we use the 2nd equation, then y = 7(-1) + 11, or y = 11-7, or y = 4.

The solution of this system of linear equations is (-1, 4)

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

the two may have that, even a breakdown is probably offered
