Answer:
y = 3x - 4 answer x = 11/3
4x + 3y = 1 answer -3/4y + 1/4
2-3x = y answer -1/3y + 2/3
Answer:
<u>no solution</u>
Step-by-step explanation:
6x + 10 = 6x + 21
<em>combine like terms</em>
6x - 6x = 21 - 10

Answer:
Step-by-step explanation:
Because of the Isosceles Triangle Theorem, angle B and angle C have the same measure. If angle B is 75, then so is angle C. By the Triangle Angle-Sum Theorem, all the angles of a triangle have to add up to equal 180 degrees. That means that angle A = 180 - 75 - 75 which is 30 degrees. Therefore,
Angle A = 30 degrees. By the substitution property of equality,
4y + 10 = 30 and
4y = 20 so
y = 5
