Question

Determine which of the following equations are linear equations in x.

a) 2x+x-3=0
b) 14=x²
c) 8x-3=8
d) 2x + 7y=6

Determine which of the following equations are linear equations. Select all that apply.
A. 2x+7y=6
B. 2x+x-3=0
C. 14=x²
D. 8x-3=8

Answer 1

1) A and B

2) B only

Explanation:

1) In mathematics, a linear equation is an equation that may be put in the form
`{\displaystyle a_(1)x_(1)+\ldots +a_(n)x_(n)+b=0, }` where
`x_(1)`,
`\ldots, x_(n)` are the variables, and
`{\displaystyle b, a_(1), \ldots, a_(n)}`are the coefficients, which are often real numbers.

Therefore, in the first question only A and B are the answers
