Answer:

a = 1, b = 3.

Step-by-step explanation:

a + b = 4

a - b = -2 Adding to eliminate b:

2a = 2

a = 1

So 1 + b = 4

giving b = 3.

Step-by-step explanation:

x + y = 3 ---------------- eqn 1

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

Substitute y for -6x + 3 in equation 1

x + -6x + 3 = 3

x - 6x + 3 = 3

-5x + 3 = 3

Collect like terms

-5x = 3 - 3

-5x = 0

Divide both sides by -5

x = 0

Hope this helped!
