Answer:
see explanation
Step-by-step explanation:
Given the 2 equations
2x + 3y = 10 → (1)
x + y = 7 → (2)
Multiplying (2) by - 3 and adding to (1) will eliminate y
- 3x - 3y = - 21 → (3)
Add (1) and (3) term by term to eliminate y, that is
- x = - 11 ( multiply both sides by - 1 )
x = 11
Substitute x = 11 into either of the 2 equations and evaluate for y
Substituting into (2)
11 + y = 7 ( subtract 11 from both sides )
y = - 4
Solution is (11, - 4 )
