4.5(4 − ) + 36 = 202 − 2.5(3 + 28)<br><br>Step by Step please
PolarNik [594]

Ok so first off you need to get rid of the clauses in the equation.

So 4.5 ( -4) becomes -18 and -2.5(3+28) becomes -77.5

-18 + 36 = 202 - 77.5

Now you are going to solve the equation.

18 = 122.5

Hope this helped ;),

35=3x+14 could anyone help me fast please I also need to show work!
Neporo4naja [7]

Answer:

\boxed {\tt x=7}

Step-by-step explanation:

We are given the equation

35=3x+14

We want to solve for x, therefore we must isolate x on one side of the equation.

14 is being added to 3x. The inverse of addition is subtraction. Subtract 14 from both sides of the equation.

35-14=3x+14-14

35-14=3x

21=3x

x is being multiplied by 3. The inverse of multiplication is division. Divide both sides of the equation by 3.

\frac{21}{3} =\frac {3x}{3}

\frac{21}{3}=x

7=x

Let's check our solution. Plug 7 in for x and solve.

35=3x+14

35=3(7)+14

35=21+14

35=35

This checks out, so we know our solution, <u>x=7 </u>is correct.

Which is a solution to the equation?<br> (x - 3)(x - 5) = 35<br> x= -8<br> x=-5<br> x=2<br> x = 10
JulijaS [17]

(x-3)(x-5)=35

Multiply the brackets together

x*x-5*x-3*x-3*5

x^2-8x+15=35

Move +35 to the other side. Sign changes from +35 to -35

x^2-8x+15-35=35-35

x^2-8x-20=0

(x-10)(x+2)=0

x-10=0     x+2=0

Move -10 to the other side. Sign changes from -10 to +10

x-10+10=0+10   x+2-2=0-2

 x=10                      x=-2

Answer: x=10
