Hello, and welcome to Brainly!
It seems y ou want to find the value of x in the expression -4x + 7 - 6 = 22.
If that's the case, combine the 7 and -6, obtaining: -4x + 1 = 22. We want to isolate x. To achieve this, subtract 1 from both sides, obtaining -4x = 21.
Dividing both sides of this equation by -4 gives us x = (-21)/4.
This is the "solution" of the given equation.

X =26 I know it’s not on the but that’s the right answer
Answer:
B = 3
Step-by-step explanation:
3x + 15 = 4x + 12
= 15-12=4x-3x
= 3 = x
X = 3
Answer:
4250 km
Step-by-step explanation:
If we convert 25/6 into a mixed fraction, we get 4 1/6. Since we already know the plane goes for four hours already, we can multiply 1020 km x 4. That would give us 4080. Now that we converted the equation into a mixed fraction, we also know that the plane goes for an extra 1/6 hour. We divide 1020/6 because it is a sixth of an hour and the plane can travel 1020 in an hour. We get 170 km for 1/6 of an hour.
4080km + 170km= 4250 km
