Question

Solve the equation 7-(5t-13)=-25-15b+21+5b=-19

Answer 1

Let's solve the following expressions:

a.) 7 - (5t - 13) = -25

`\text{ 7 - (5t - 13) = -25}`
`\text{ 7 - 5t + 13 = -25}`
`\text{ 20 - 5t = -25}`
`\text{-5t = -25 - 20}`
`\text{-5t = -4}5`
`\frac{\text{-5t}}{-5}\text{ = }\frac{\text{-4}5}{-5}`
`\text{ t = 9}`

Therefore, t = 9

b.) -15b + 21 + 5b = -19

`-15b+21+5b=-19`
`-10b+21=-19`
`-10b=-19\text{ - 21}`
`-10b=-40`
`(-10b)/(-10)=(-40)/(-10)`
`\text{ b = 4}`

Therefore, b = 4
