Step-by-step explanation:

substitute y = 7x + 3 in equation 2

9x - 2y = 14

9x - 2(7x + 3) = 14

9x - 14x + 6 = 14

-5x + 6 = 14

-5x = 14 - 6

x = 8 ÷ 5

x = 1.6

subs x = 1.6 into equation 1

y = 7x + 3

y = 7(1.6) + 3

y = 11.2 + 3

y = 14.2

thus, x = 1.6, y = 14.2

Write the following equation in slope intercept form. 12x + 4y = -4

Vlada [557]

Answer:

y=-3x-1

Step-by-step explanation:

12x+4y=-4

Slope intercept y=mx+b

Subtract 12x from both sides

4y=-4-12x

Divide each side by 4

y=-1-3x then just reorder to match slope intercept form

y=3x-1
