Answer as a decimal: 
Answer as a fraction: 
Step-by-step explanation:
y - 15 = 3x
-2x + 5y = -3
Solve the first equation first to substitute into second equation
y - 15 = 3x
Add 15 to both sides of the equation
y = 3x + 15
Substitute this value of y into second equation
-2x + 5y = -3
2x + 5(3x + 15) = -3
Multiply
2x + 15x + 75 = -3
Add the x's
17x + 75 = -3
Subtract 75 from both sides of the equation
17x = -78
Divide both sides of the equation by 17

what is like prove and explaine
Step-by-step explanation:
Answer:
10 and 3
Step-by-step explanation:
let the first number be x and the second be y
x=y+7------i
their sum is 13
x+y=13-----ii
substituting for x in ii
y+7+y=13
collecting like terms
2y=13-7
2y=6
y=3
recall ii and substitute for y
x+y=13
x+3=13
collecting like terms
x=10
