How to solve ? [3x+4]+1=7

Mathematics
1 answer:
Vinil7 [7]3 years ago
6 0

to solve this we need to isolate the x variable.

subtract 1 from each side: [3x+4] = 6

now we can drop the parentheses and subtract 4 from each side: 3x = 2

divide each side by 3: x = 2/3

Wht is 84 is 74% of what number
Elina [12.6K]
'is' in mathematics means equal
'of' in mathematics means multiplication

percent means over 100

84 = 74% * x

84 = 74/100 * x

84 = 37/50 * x

Multiply 50/37 on both sides, so we can isolate 'x'

85 * 50/37 = x

x = 4250/37

x ≈ 114.864865

84 is 74 percent of <span>114.86</span>.
