Y = 3x - 8<br>y = 4 - X​
mihalych1998 [28]

Answer:

Step-by-step explanation:

Using substitution method.

y = 3x - 8  -------(i)

y = 4 - x -------- (ii)

Substitute y = 3x-8 in equation (ii)

3x -  8= 4 - x                      {Add x to both sides}

3x - 8 + x = 4 - x +x

4x - 8 = 4         {Add 8 to both sides}

4x = 4 + 8

4x = 12    {Divide both sides by 4}

x = 12/4

x = 3

Substitute x = 3 in Equation (i)

y = 3*3 - 8

y = 9 - 8

y = 1
