2 answers:
hi there,
Let's solve your equation step-by-step.
2(x−7)−3(x−4)=1
Step 1: Simplify both sides of the equation.
2(x−7)−3(x−4)=1
(2)(x)+(2)(−7)+(−3)(x)+(−3)(−4)=1(Distribute)
2x+−14+−3x+12=1
(2x+−3x)+(−14+12)=1(Combine Like Terms)
−x+−2=1
−x−2=1
Step 2: Add 2 to both sides.
−x−2+2=1+2
−x=3
Step 3: Divide both sides by -1.
−x
−1

−1
x=−3
Answer:
x=−3
First use the rule a(b+c)=ab+bc 2x - 14 - 3x + 12 = 1 Then, combine like terms -1x - 2 = 1 Now, multiply both sides of the equation by -1, and then subtract 2 from both sides. The result: x = -3
