m-7 = 13
h + 6 = 18
k-2= 23
f + 9 = 24
x + 2.5 = 5
a-1.6 = 3
y + 3.9 = 5.1
b-4.3 = 2.7​

Answer 1

Respuesta:

a-3 = 12   / 15-3=12

y + 8 = 16  / 8+8=16

b - 10 = 5  / 15-10=5

x + 4 = 9  / 5+4=9

x = 9-4  / x=5

X = 5

5 + 4 =9  / 9 = 9

m-7 = 13  / 20-7=13

h + 6 = 18  / 12+6=18

k-2= 23  / 25-2=23

f + 9 = 24  /15+9=24

x + 2.5 = 5  / 2.5+2.5=5

a-1.6 = 3  / 1.4+1.6=3

y + 3.9 = 5.1  / 1.2+3.9=5.1

b-4.3 = 2.7​ /

Simplifying

x + 4.3 = 2.7

Reorder the terms:

4.3 + x = 2.7

Solving

4.3 + x = 2.7

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4.3' to each side of the equation.

4.3 + -4.3 + x = 2.7 + -4.3

Combine like terms: 4.3 + -4.3 = 0.0

0.0 + x = 2.7 + -4.3

x = 2.7 + -4.3

Combine like terms: 2.7 + -4.3 = -1.6

x = -1.6

Simplifying

x = -1.6
