Answer:

Step-by-step explanation:

equation 1. 6a + 2b = 14 ( times this equation by -2)

equation 2. 2a + 4b = 18

equation 1 becomes -12a - 4b = -28

equation 2. remains. 2a + 4b = 18

Cancel out the b’s

-10 a = -10 (Divide both sides by -10)

a = 1

substitute 1 for a to find b

i think your numbers in the problem you gave is not accurate though

please check it again

b = 4
