Answer:
26
Step-by-step explanation:
4(x-4)-3x=10
- Rule = a(b + c) = ab + ac
- Rule = a(b - c) = ab - ac
4(x-4) = 4x - 16
4(x-4)-3x=10
4x - 16 - 3x = 10
x - 16 = 10
x -16 +16 = 10 +16
x = 26
Hope this helps ^-^

Answer:
x = 25
y = 65
Step-by-step explanation:
(I did it on Math Nation)
180 = 130 + 2x
50 = 2x
x = 25
180 = 50 + 2y
130 = 2y
y = 65
As always, the sum of the measures of the angles in a triangle is 180°.
(x -5) +(3x +30) +35 = 180
4x +60 = 180 . . . . . . . . . . . . . collect terms
4x = 120 . . . . . . . . . . . . . . . . . subtract 60
x = 30 . . . . . . . . . . . . . . . . . divide by 4
a) The value of x is 30.
