Answer: x=18
im assuming that this is a right angle
so if it is then that means the total of the angle should be 90 degrees. so 2x+3x should be equal to 90. Just combine like terms to get that 5x=90 and then isolate the variable (divide by 5 on both sides) so x ends up equaling 18.
so x=18
Answer:
Step-by-step explanation:
a - 3b = 4 ---------------(eq1)
2a = 6b -9
or, 2a - 6b = -9 ------------(eq2)
2a - 6b = 8 --------(eq1) X 2
2a - 6b = -9 --------(eq2)
(-) (+) (+)
_________________________________
the variable part of both the equations are same. so the equation has more than one solution.
