Answer:
-7Q + 6 + 5Q = 15 - 7 Answer: q=−1
p+5+p=3(2+p) Answer: p=−1
(A + 4) + 6A = 2 (2 + 3A) Answer: a=0
Step-by-step explanation:
−7q+6+5q=15−7
Step 1: Simplify both sides of the equation.
−7q+6+5q=15−7
−7q+6+5q=15+−7
(−7q+5q)+(6)=(15+−7)(Combine Like Terms)
−2q+6=8
−2q+6=8
Step 2: Subtract 6 from both sides.
−2q+6−6=8−6
−2q=2
Step 3: Divide both sides by -2.
−2q/−2=2/−2
q=−1
p+5+p=3(2+p)
step 1: Simplify both sides of the equation.
p+5+p=3(2+p)
p+5+p=(3)(2)+(3)(p)(Distribute)
p+5+p=6+3p
(p+p)+(5)=3p+6(Combine Like Terms)
2p+5=3p+6
2p+5=3p+6
Step 2: Subtract 3p from both sides.
2p+5−3p=3p+6−3p
−p+5=6
Step 3: Subtract 5 from both sides.
−p+5−5=6−5
−p=1
Step 4: Divide both sides by -1.
−p/−1=1/−1
p=−1
a+4+6a=2(2+3a)
Step 1: Simplify both sides of the equation.
a+4+6a=2(2+3a)
a+4+6a=(2)(2)+(2)(3a)(Distribute)
a+4+6a=4+6a
(a+6a)+(4)=6a+4(Combine Like Terms)
7a+4=6a+4
7a+4=6a+4
Step 2: Subtract 6a from both sides.
7a+4−6a=6a+4−6a
a+4=4
Step 3: Subtract 4 from both sides.
a+4−4=4−4
a=0
