Answer:
(1,2)
y=2
x=1
Step-by-step explanation:
x+y=3
3x+5y=13
solve the equation
x=3-y
3x+5y=13
substitute the value of x into an equation
3(3-y)+5y=13
distribute
9-3y+5y=13
add -3y to 5y
9+2y=13
subtract 9 from both sides
2y=4
divide both sides by 2
y=2
substitute the value of y into an equation
x=3-2
subtract 3 to 2
x=1

Answer:
x=0
Step-by-step explanation:
2(3x - 1) + 2(4x + 5) = 8
Distribute
6x -2 +8x +10 =8
Combine like terms
14x +8 = 8
Subtract 8 from each side
14x+8-8=8-8
14x =0
Divide each side by 14
14x/14 = 0/14
x=0
