Answer:
t = 5
Step-by-step explanation:
Given
t + 2 = 7 ( isolate t by subtracting 2 from both sides )
t = 7 - 2 = 5
Multiply the top equation by 6 and the bottom equation by 7. You will cancel x first by doing this and solve for y. You should get y=-1.
Substitute in y for either original equation.
You should get x=1.
Solution is (1,-1).
