What is the value of x in the following? 40x + 7=2x × 12 - 16​

Mathematics
1 answer:
Mumz [18]2 years ago
8 0

Answer:

x = -1.4375

Step-by-step explanation:

Multiply the monomials: 40x + 7 = 24x - 16

Rearrange unknown terms to the left side of the equation: 40x-24x=-16-7

Combine like terms: 16x=-16-7

Calculate the sum or difference: 16x = -23

Divide both sides of the equation by the coefficient of variable: x = -23÷16

Calculate the product or quotient: x=-1.4375

Answer:

13) 25 and 17

14) cupcakes = $5

brownies = $3

Step-by-step explanation:

13)  you can set this up as equations

so x + y = 42

x-y = 8

solve simultaneously by subtracting from each other

2y = 34

y= 17

if y = 17

42 - 17 = 25 = x

14) set up as equations again

Ben    7c + 10b = 65

franklin   7c +7b = 56

subtract from eachother

3b = 9

b = $3

7c + 10(3) = 65

7c = 35

c = $5
