Answer:
a = 4, b = 3
Step-by-step explanation:
7a = 28
a = 4
5(4) - 2b = 14
2b = 6
b = 3
b= 3
Add equations togther
5a - 2b = 14
2a + 2b = 14
7a + 0 = 28
devide by seven
plug in a
2(4) + 2b = 14
8 + 2b =14
subtract a
devide by 2
10y-11
2x in common (slope)
similar because they both have a slope of 2
different because the 2nd equation has a y intercept of 3
