Answer:
a = 4 , b = 2
Step-by-step explanation:
4a - 3b = 10 → (1)
2a + b = 10 → (2)
Multiplying (2) by 3 and adding to (1) will eliminate the b- term
6a + 3b = 30 → (3)
Add (1) and (3) term by term to eliminate b
10a + 0 = 40
10a = 40 ( divide both sides by 10 )
a = 4
Substitute a = 4 into either of the 2 equations and solve for b
Substituting into (2)
2(4) + b = 10
8 + b = 10 ( subtract 8 from both sides )
b = 2
