Solve: 2x+1-14x=-71<br> This is for 7th grade mathematics. Please help! I need this now!

S_A_V [24]

Answer:

The solution is $x=6$

Step-by-step explanation:

The given equation is $2x+1-14x=-71$

We group like terms to obtain;

$2x-14x=-71-1$

We now simplify to get;

$-12x=-72$

We divide both sides of the equation by -12 to get;

$\frac{-12x}{-12}=\frac{-72}{-12}$

We cancel out the common factors to get;

$x=\frac{72}{12}$

This implies that

$x=\frac{12\times 6}{12}$

$x=6$

2 lines form intersecting at a right angle a. form a line b. are parallel b. are perpendicular c. form a ray

Nonamiya [84]

Two lines intersecting at a right angle would be perpendicular. Parallel lines do not cross or touch each other, and rats don’t form right angles. Perpendicular lines are horizontal and vertical crossing together to form a right angle.
