  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

y = -3x + 10

y = -2x + 6

<u>Step 2: Solve for </u><em><u>x</u></em>

<em>Substitution</em>

  1. Substitute in <em>y</em>:                         -3x + 10 = -2x + 6
  2. Add 3x on both sides:             10 = x + 6
  3. Isolate <em>x</em>:                                   4 = x
  4. Rewrite:                                    x = 4

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Define equation:                    y = -2x + 6
  2. Substitute in <em>x</em>:                       y = -2(4) + 6
  3. Multiply:                                  y = -8 + 6
  4. Add:                                        y = -2

Enter the sum of numbers as a product of their GCF. 75 + 30 The sum of the numbers as a product of their GCF is
Oksanka [162]

Answer: 75+30 = 15 x 7

Step-by-step explanation:

The given expression is 75+30 (=105) which defines the sum of 75 and 30.

Prime factorization of 75 and 30 are as below:

75 = 5 x 5 x 3

30 = 5 x 3 x 2

GCD (75,30) = 5x 3 = 15  [Note: GCD = Greatest common divisor]

Consider 75+30 = (15 x 5) + (15 x 2)   [75 = 15 x 5 and 30= 15 x 2]

=  15 (5+2)   [taking 15 as common ]

= 15 x (7)

(=105)

So,  75+30 which is sum of the numbers and it is expressed as 15 x 7 which  a product of their GCF.
