Answer:
a = 4
b = 5
Step by Step:
Solve for
a in the first equation.
a = 23 −3b
2 2
6a − 4b = 4
Replace all occurrences of a in 6a − 4b = 4 with
23 −3b
2 2
a = 23 − 3b
2 2
6 ( 23 − 3b ) − 4b = 4
2 2
Simplify 6 ( 23 − 3b )− 4b
2 2
a = 23 − 3b
2 2
69 − 13b = 4
Solve for b in the second equation.
a = 23 −3b
2 2
b = 5
Replace all occurrences of b in a = 23 −3b with 5
2 2
a = 23 − 3(5)
2 2
b = 5
Simplify
23 − 3(5)
2 2
a = 4
b = 5
