I Need help plz and thank you Solve each system using the elimination method.

4.6.1) 4a + 7b = 1
-2a + 7b = -5

A. Subtract −+ -2a + 7b = -5 ab from the other equation so the b-terms become opposites. Then, rewrite the system so there are no parentheses.
→
B. Now, add the equations from Step A vertically.

C. Solve the equation in one variable for that variable.

D. Substitute the result from the previous step into 4a + 7b = 1 and simplify.

E. Write the solution for the system.

F. Check the solution with the original equation not used in Step D.

if that does not make sense get in this https://kami. app/ThejMK2xzf12
