How to solve this equation 3y-2x=4 in terms of x

The measure of <SPQ in this rhombus is 126

Step-by-step explanation:

Step-1

write the given question

m<SPR= (2x + 13)°

m<QPR= (3X-12)°

Step-2

Set SPR and QPR equal

2x+13=3x-12

Step-3

add it all up

3x-2x-12-13=0

x=25

Step-4

substitute in the question  

2(25)+13=63 and 3(25)-12=63

both equal 63

Step-5

Add 63+63

=126
