Answer:
x=17.7 y=27.4
Step-by-step explanation:
We should start with the equation with only 1 variable.
4x-4+6x+7= 180
Solve.
10x+3=180
10x=177
x=17.7
3y-20+4x-7 should equal 180.
So solve.
3y-27+4x=180
Substitute for x.
3y-27+4(17.7)=180
Solve.
3y-27+70.8=180
3y=82.2
y=27.4
Answer:
x = 10 , y = 29
Step-by-step explanation:
The angle vertically opposite (4x - 7) is congruent , then
4x - 7 and 6x + 7 are same- side interior angles and sum to 180° , so
4x - 7 + 6x + 7 = 180
10x = 180 ( divide both sides by 10 )
x = 10
Then
6x + 7 = 6(10) + 7 = 60 + 7 = 67
3y - 20 is vertically opposite 6x + 7 and is congruent , that is
3y - 20 = 67 ( add 20 to both sides )
3y = 87 ( divide both sides by 3 )
y = 29
