Question

2x+4+8(6*6+7)+5x+7=45

Answer 1

Answer:

2x+4+8(6*6+7)+5x+7=45

2x+12(43)+5x+7=45

2x+516+5x+7=45

2x+5x+7-516=45

7x-509=45

7x=45+509

7x=554

$x = \frac{554}{7}$

x=79.14

Answer 2

2x+4+8(36+7)+5x+7=45

2x+4+8(43)+5x+7=45

2x+4+344+5x+7=45

7x+355-45=0

7x+310=0

7x= -310

x= -310/7

x= -44.28
