No solution
It’s no solution because if you would’ve subtracted 4.5z on both sides then the equation would’ve become:
0= -4.25+6.25
Which makes it a no solution since you can’t really solve the equation.
Answer:
x = 9 y = 3 (9,3)
Step-by-step explanation:
3x - 5y = 12
3(3y) - 5y = 12
9y - 5y = 12
4y = 12
4y/4 = 12/4
y = 3
x = 3(3)
x = 9
CHECK:
3(9) - 5(3) = 12
27 - 15 = 12
12 = 12
