Answer:
<em>(2.5, 3.75), or using fractions, (5/2, 15/4)</em>
Step-by-step explanation:
3x - 2y = 0
x + 2y = 10
Add the equations and solve for x.
4x = 10
x = 2.5
Substitute x = 2.5 in the first equation, and solve for y.
3(2.5) - 2y = 0
-2y = -7.5
y = 3.75
Answer:
x=31
Step-by-step explanation:
you just have to add the two equations to equal 180 because it's they're supplementary angles.
(25+x)+4x=180
25+x+4x=180
25+5x=180
5x=155
x=31
