Solve the system of liner equations using a table 1. y = x + 1
y = 2x - 3

2. y = x - 3
y = -2x + 6

solve the system of liner equations using a graph.

1. y = x - 3
y = -1/2x

2. y = -x -2
y = 5/2x + 5

solve the system of liner equations algebraically.

1. x + y = 19
y = x - 5

2. y - x = 14
y = 3x + 6

2. y = -x -2

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15

i think it’s c i believe

the value of x is 28.2
