What is 2x+3=x-4 i really need on this question

Subtract x from both sides

2x + 3 - x = -4

Simplify 2x + 3 - x to x + 3

x + 3 = -4

Subtract 3 from both sides

x = -4 - 3

Simplify -4 - 3 to -7

x = -7

2x+3=x-4

2x-x= -4-3

x= -7

Check answer by using substitution method

2(-7)+3= -7-4

-14+3=-11

-11=-11

Answer is x=-7

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

37 = ending with 7

unit's digit in the cube..3

56 = ending with 6

unit's digit in the cube..2

133 = ending with

unit's digit in the cube..7
